'''Alfred William Benn''' (1843–1915) was an agnostic
and an honorary associate of the Rationalist Press Association
. His book ''[https://archive.org/details/historyofmodernp00benniala A History of Modern Philosophy]'' (first published in 1912) was republished in the Thinker's Library
series in 1930.
He was the author of ''The Greek Philosophers'' (2 vols, 1882); ''The History of English Rationalism in the Nineteenth Century'' (2 vols, 1906); and ''The History of Ancient and Modern Philosophy'' (2 vols, 1912).
Benn was also a member of the London Positivist Society
and a friend of the lawyer and positivist Vernon Lushington. Lushington's daughter Susan recorded in her diary on 3 September 1889 that Benn and his wife visited the Lushington's Surrey home - Pyports, Cobham - and how Mrs Benn told her "how she came to be a positivist."
